After the first four play-off holes had been halved in par-par-bogey-par, Mark Wiebe won the 2013 Senior Open Championship Presented by Rolex at the fifth trip down the par four 18th at Birkdale, two-putting as Bernhard Langer failed to get up and down from in front of the green. The first two holes of the sudden-death contest were played on Sunday evening before darkness forced an 8am resumption on Monday morning.
